The vadose zone is the Earth's terrestrial subsurface that extends from the surface to the regional groundwater table. As shown in Figure 1, the vadose zone includes surface soil, unsaturated subsurface materials, and a transiently inundated capillary fringe.

The governing equations are not always realistic (usually a minor problem for flow models). 2. Discretization (subdivision) of the modeled region requires averaging of vadose zone properties in space and averaging system changes w.r.t. time.

The vadose zone is known to play a critical role within the biosphere: (1) as a storage medium to supply water to the plants and atmosphere, and (2) as a controlling agent in the transmission of recharging water as well as contaminants from the land surface to groundwater . Past interest in the vadose zone has largely been a result of public concern about the need to protect groundwater reserves for drinking and agricultural purposes.

The vadose zone can be shallow or very deep depending on how far below the surface is the water table. Vadose Zone and Soil Studies Texas Soil Observation Network (TxSON) Texas Soil Moisture Observation Network (TxSON) is an intensively-monitored 36 km grid cell (1300 km2) located near Fredericksburg, Texas, along the Pedernales River and within the middle reaches of the lower Colorado River. The vadose zone can be characterized as a complex subsurface system in which intricate physical and biogeochemical processes occur in response to a variety of natural forces and human activities.

What is Vadose Zone? (1) Located below land surface and above groundwater level (2) Contains the thee-phases of solid, liquid, and gas Solid phase: mineral grains (soil formed by in situ weathering, sediment transported from somewhere else, unweathered bedrock) and organic matter (the remains of plants and animals under decay) The vadose zone is known to play a critical role within the biosphere: (1) as a storage medium to supply water to the plants and atmosphere, and (2) as a controlling agent in the transmission of recharging water as well as contaminants from the land surface to groundwater . Past interest in the vadose zone has largely been a result of public concern about the need to protect groundwater reserves for drinking and agricultural purposes. (b) Vadose zone monitoring shall not be used as the sole release detection method of non-visual monitoring where the monitoring well cannot be located within the backfill surrounding the tank, or where the existing ground water level or the highest anticipated ground water level, including intermittent perched ground water, is less than 10 feet below the bottom of the tank. Vadose Zone Research Group in Biological & Agricultural Engineering Department at Texas A&M University 301C Scoates Hall, 2117 TAMU College Station, TX 77843-2117; bmohanty@tamu.edu; Phone: 979-458-4421; 979-845-3932 Provided that there is no impermeable layer above, then the upper level of this saturated zone is called water table. Above the water table is the zone of aeration and water present in this unsaturated zone is called vadose water including the zone of soil moisture (Chapter 2 ). The vadose zone (also known as the unsaturated zone) refers to the area from the ground surface to the water table.

The prior modeling studies incorporated solid-phase adsorption for the transport of surfactants, but not fluid-fluid interfacial adsorption.

This is a brief overview of the vadose zone and soil porosity.

The vadose zone is the interval between the crop root zone and the water table, and is a critically important region for storage, transport and transformation of chemicals that can impact groundwater quality.
